Arkuni, not putting down the premium content, but maybe you could put in an update so you can earn 'premium points'? These would have to be hard to get, and as an option, you could buy them instead of finishing the campaign for the umpteenth time or something like that... Otherwise, awesome game, one of my favourites on Kong.
